PURPOSE: Provided is a light-emitting mixed polymer composition, which enables the patterning by a laser transfer and improves the transfer property including the pattern uniformity and transfer efficiency. CONSTITUTION: The light-emitting mixed polymer composition is for use in an organic electro-luminescence device comprising an anode, a hole transport layer, an emission layer and a cathode. The light-emitting mixed polymer composition is characterized by comprising: two or more light-emitting polymers that have different interfacial properties and different light-emitting ranges in which an overlap zone is present between the light-emitting spectrum zone of at least one of first light-emitting polymers and the light-emitting spectrum zone of at least one of second light-emitting polymers; and an additive which is optically non-reactive or has charge transportability, improves the adhesion between a substrate and the emission layer and reduces the cohesive force between the light-emitting polymers to facilitate the separation of the polymers after the transfer process. |
